View Full Version : HELP: no divx can fit on a cd

11th December 2004, 02:37
I have noticed that everytime I use Gordian Knot to convert a DVD film into Divx and select to fit 1 CD (700MB) - the final divx film is always around 10MB more. Now I got a dozen divx films between 710-720MB and none of them can fit on a CD. Is it because of the mp3 audio being added ontop of the 700MB film? I don't think so.

Anyway, what's the best way to downsize these over-large divx files? do I have to decode and re-encode them again? using gordian knot? what's the fastest way to fix this cd burning problem?

Moved to GK forum.

Without seeing a log file (<movie>_gknot.log) its impossible to say whether or not there is some procedural problem causing size overages.


While we're waiting to see it, there are several alternatives in order to reduce size, such as: You can cut off the last few megabytes if you wish, see: www.doom9.org/vdubmod-procedures.htm.

You could re-encode just your soundtrack at a lower bitrate with BeSweet and then remux with the existing video (see vdubmod-procedures link).

You may be able to overburn your 710MB files, though that will depend on your burning software, your burner, and your CD-R media.

And are you sure it's really 710-720 MB, and not, for example, 717,000 KB?

Here's the sizes of Troy CD1 (inc. 3MB subtitles file):

Size: 707 MB (741,912,576 bytes)
Size on disk: 707 MB (741,916,672 bytes)

And even without the 3MB subtitles file Troy.avi alone is:

Size: 702 MB (736,102,400 bytes)

Sizes of Troy CD2 (inc. 3MB subtitles file):

Size: 704 MB (739,076,096 bytes)
Size on disk: 704 MB (739,078,144 bytes)

Okay, here's a good example of Arahan:

Size: 700 MB (734,506,323 bytes)
Size on disk: 700 MB (734,511,104 bytes)

Will that fit on a 700MB CD safely? I notice the film is exactly 700MB but then there's the subtitles file. Will the subtitles not get burned on the CD?

If you don't account external subs then GK produces perfectly normal results - it is expected to have +-2Mb difference per 700Mb for some cases. To take into account subs during encoding time you have to selected them as "Files" on the bitrate tab.
